Settings were coin program, auto sens +3, gain at 6 (like deep targets to sound deep),high trash, detect deep and fast...Pulled out alot of zinc pennys and they were jumping all over the place in this one little area on smart screen so I x'd those numbers out...Found a square tab at 5 inches??????..like what the hell and it was under a old tree taggled in the roots(had to cut alot of roots to get to it)...The ID numbers on like everything seem to jump all over the place, the tone helped alot sort of like the original minelab back 20 years ago..hmmm.. Im starting to think these ferrous and conductivity numbers were just put there for eye candy and there really hasn't been any advancement from the original minelab..I'm getting discouraged
